Abstract

The catabolic and energy-dissipating actions of mitochondrial uncoupling proteins (UCPs) conflict with many of the bioenergetic hallmarks of malignancy. We have recently demonstrated that overexpression of mitochondrial uncoupling protein 3 (Ucp3) in the basal epidermis impedes skin tumorigenesis through a novel pathway of thymoma viral proto-oncogene 1 (Akt1) inhibition via increased mitochondrial lipid catabolism.

Keywords: Akt; UCP3; keratinocytes; lipid catabolism; metabolomics; mitochondria; skin cancer; uncoupling; uncoupling proteins
